Use the Batarang to stun the remaining goons on the ground from corner cover spots and use a ground takedown on each. Immediately grapple up to a gargoyle to lose the attention of the remaining enemies. The nearest of the three enemies can be dealt with via a stealth takedown by swooping in behind him. Now that the room is full of armed goons, you'll want to remain in a lofty position. This high ledge has a Chronicle of Arkham marker on it ( Arkham Mansion Riddle #4). Hop down here for a Riddler Trophy.Back in the Main Hall, you should immediately grapple up to the balcony above the fallen bell / statue. In the Botanical Glasshouse, check out the second level for a removable section of grates over a trench. Drop into the trench below and take it south to the center of the room. In the Abandoned Chamber, drop to the ground level and, after dealing with the lunatic, search for a grate on the ground in the north section. You can Line Launch to it from the middle area - you'll have to climb a bit to get there (cut down the suspended walkway in the south with a Batarang to get to the highest area). Pull this down with your Ultra Batclaw, then Line Launch to the alcove with this trophy.

High on the west wall of the Abandoned Chamber is a weakened wall panel. Just as you enter the Botanical Gardens from Arkham West, turn left and take an environmental scan of the slumped guards on a bench. Snap a shot of this while zoomed in to solve the area's riddle. It's a bit lower and to the right of one of the large, hooded statues supporting the roof. In the Aviary, on the west wall, is a skeleton hanging out of what appears to be a cocoon of some sort.

There's no closet in the Gardens, so someone is using the roof instead.

Go to the northeast portion of the Flooded Corridor and look for the bench with the Poison Ivy Interview Tape on it. To the right is the Botanical Gardens Secrets Map. With the Cryptographic Range Amplifier upgrade (get this early!), you can use your Cryptographic Sequencer to hack the panel inside this small hideout.

Grapple up high in the Glasshouse Generator Room to find a security door. Zoom in on and scan it to solve a Riddle. Go to the northeast portion of the Flooded Corridor and examine the plaque on the planter. Is this a tribute to what mad dog left behind?.Zoom in on these dolls and scan them to solve the riddle. In the Flooded Corridor, find the northern side of the collapsed portion of hallway and look for a bench with a pile of dolls on it nearby. Looks like all the king's horses trampled all the king's men.Batman: Arkham Asylum The Riddler's Challenge «
